Tocllwkom it may concern:

B'eitknown that I, JoHN E. SAMonLson, ,apitizen of the United States, residing at \aOjphiem, in the county of Henry, State of 5,,Illi nois, have invented certain new and usefullrnprovements in Two-Row Cultivators; ,tandl. do hereby declare the following to be alfull, clear, and exactdescription of the invention, such as will enable others skilled iii-the art to which it appertains to make @nd use the same.

Thisinjention relates to agricultural ma- =chinery, and has particular reference to improvements in two-row cultivators. 15. The primary construct a two-row cultivator of the motordri ven type in which the cultivatingele inents pofi sess' a wide range of adjustability. =;.In';' this connectiom-it. is the purpose to onstructza-v machine in'which the various hovel gangs are capable of both independn n 7 andjalso relative and simultaneous lateral djustment, there being additionally emodied means everatpositions of adjustment.

With the above objects in view and such other objects as may hereinafter a pear, ny invention will now be'fully set fort and described, reference being had to the accompanying drawings;

. In the drawings a Figure 1 is a plan viewof the machine, f

view. on line of ,ig', s is a section on the line 4 4 looking in the-opposite direction, 'Fig. 5 is a fragmentary side elevation of atportion of the shovel adjusting mechanism,

A steering rod 11 extends theilength of the machine end geared v to the guide bar 8 suitably incorporated" in the frame 1 4 or vehicle, ,inorder to utilize the power of the engine 4 in transportation.

.hasits rear end-suitably locatedtobecona I nected to a wagon, plow or other implement The frames 13 consistfof rearwardly di vergent arms Whose forward ends arev continued in the swinging bars .14 whose for ward ends are upturned to connect, by means of joints 14' to the vertical shafts'15 which are, vertically adjustable in the sleeves 22 fmounted upon the transverse frame member.

or beam 16, adjusting screws 25 securing the shafts 15, in the sleeves 22. Therear ends of the arms formed in the frames 13 are brought together abruptly to-provide the Y the may be located "in suitably spaced relatiori: The vertical rods 9 are pivotedupon the frames 13 by means of the brackets 31, the latter being mounted inbetween the arms 13' having the rods 9. pivoted thereto-to swing transversely of the'machine. Racks 32 mounted across the frames 13 in proximity to the'rods 9 areada'pted to be engaged by the locking paWls 33 mounted upon the standards 9 and controlled by the rods 34 whose opposite ends connect to the hand levers 35. The hand'levers 35 are carried by the boxes or housings 38' which are adjustably mounted upon the upper ends of the rods 9 and are adjustable thereonby means of the bolts 37, the latter engaging the teeth 36 of-the bars 9 which provlde racks along the edges of the-latter. Also slidably mounted upon the bars-9iwithin the range of the rack teeth. 36 are. the housings 38.- Opposite the teeth "36 the,housings 38 carry the stud shaft .39 win tend therein in diagonal relationand..sup-. port the spirahgears 4 1 which; mesh with the rack 36. 'CrankarmS- LO' mounted upon. the outer faces of the gears 41 provide means for rotating the latter so-: asto--;adjust the 'ch exg bars 9 vertically with relation to thecasings or housings 38,- therebyraisingorlowering the shovelframes 13 independently of one another. The housings 38. are held in rigid relation to the bars 9 by means of the upwardly and i:earwardly extending brackets 43 which are secured by means of U-bolts tothe transverse shaft 45 which is mounted upon the fram 1, The shaft 45 is rotatable to raise or lower the brackets 4:3 together, a link 62, Fig. 5, pivoted at 51 to a crank arm 52 on the shaft 45 having its opposite end pivoted at 63 to a hand lever 58 for this purpose. The hand lever 58 is vertically pivoted upon a frame 58 which is suspended below the longitudinal beam 19 at one sid of the drivers position. Upon actuation of the hand lever 58, the shaft 45 is rocked to elevate or lower the several brackets 43a rack 57 cooperating with the pawl 61 and hand grip 60 providinga means for locking the rods 9 in the position of vertical adjustment. I

Also mounted upon the rock shaft 45 is a standard 66 which rises vertically above the shaft, and at its upper end is provided with a longitudinal adjusting screw 67,7t0 whose free end is secured one end of a tension 'face of the longitudinal beam 19.

spring 68 whose opposite end is connected to a second ad usting screw or bolt 75 operative-in a bracket mounted upon the inner The spring 68 tends to rock the shaft forwardly so as to normally withdraw the shovel 6 from engagement with the soil and opposite end is connected at 49 to the foot thereby assists the operator in rapidlydle- 'yating the shovel when the lever 58 is ad tuated for that purpose.

The transverse beam 4.? of theframe l is provided with a plurality-of bell crank le vers 10 mounted in horizontal relation thereon. the arm of each of the bell crank levers 10 is connected pivotally to a rod 418 whose levers 50 which are fulcrumcd at 5 1 to a frame 51 which is suspended from a trans verse beam 6 of the framework. The lower 3 ends of the foot levers 50 are provided with pedals 53 attheir lower rea r extremities so :are'extended across the machine and whose 1 outer ends are threaded to adj ustably engage joints 5 carried by the upper'ends of the swinging levers or arms 55Wl110l1 are p1v-,

oted at 84 to the suspended brackets 85, the

' latter being secured to the transverse frame member 69. The lower ends of the arms or' -levers 55 hang freely between pairs of roll-' .ersi 56 which are mounted, in brackets supported upon the shovel frames 13. Lateral oscillation of vthe rods or levers through heirods 54: and the. hell crank levers 10 jugs the frames 13 111 a like mannerupon the r forward p voted ends, the four pedals 53 permitting the selective movement of the frame. Springs 49 fixed to the frame 1 and by a link 78 to a bell crank lever' 79 whose second arm is connected to a clutch -79 by means of which the power source may be thrown into or out of engagement with the Cllli lVtttGl' mechanism. l

1 The guide/wheel 3 is mounted in a yoke removably fitted into a female yoke or frame 69. The upper end of the frame 69 is pro-,

vided with a shaft 71 which is sup orted within the front end of the machine rame. Upon the shaft 71 is-mounted the bevel gear 73 which meshes with a correspondingrgear 74 carried by the front end of thesteering rod 11, the rear end of the latter, as hereinbefore mentioned carrying the steering wheel 12 adjacent the drivers seat. The i drivers seat, which is desi ated by the numeral 65, may be supporte upon springs 64 p mounted in the frame 58.

In the operation of the foregoing mech anism, it will be observed that three distinct adjustments are provided for the cultivator.

gangs. Thus, the gangs may be collectively, raised and lowered by means of the hand lever 58. Also, they may be individually adjustcd by means of the verticallymovable rods 9 relative to the housings 38 b actua-- tion of the hand cranks 4:0, Inad 'tion to l the above, the several gangs may be 'indi vidually adjusted laterally of the machine sides of the medial lineito be adjusted to various distances upon opposite sides of the frame, the individual adjustability, of the gangs permitting the pairs upon opposite medial line. Furthermore, the gangs of each pair may be adjusted toward and from one" another in order to space them relativefto the row over which they are operating, this being accomplished by means of the foot pedals 53 and the bell crank levers 10and" the rods 54:. This adjustment ma I mental-y or temporary determine -by{the 'length cf time that the pedals are depressed, or they may be locked in adjusted position '1 by engagement of the teeth 33 in the racks 32, the teeth or pawls 33 being controlled by the hand levers 35.

bemo- From the foregoing, it is evident. thatLI 1 have provided a two-row cultivator. which,

is adapted for use'in the cultivation of corn 1 tivator gangs are set to be swung inwardly or any other growing crop. It will be noted that the adjustments are such that the cultoward the rows by actuation-of the foot y,

pedals 53, when running uncontrolled, and furthermore, immediately work away from the. row

'butam set to runstraight aheadl 1st I when the foot pedals are released, the

, springs 49 acting to return the gangs to .normal position. This is particularlyadbe set by means of the levers 35 to hold a given position throughout the cultivatin operations. When the plants are large, an

wide cultivation is desired, the two outside qbeams or gangs can be set to stand well out toward the wheels, and the two inside beams can be set closetogether, or one of the inner gangs or beamscan be removed, and the other inside gang set near the center of the machine. When the gangsare locked in this adjustable on said standards, a revolnble position, three rows can be cultivated successfully, and to particular advantage when the corn is tall and it is desirable not to cultivate too close to-the roots.

What I claim as my invention is 1. In. a cultivator, a main frame, a plurality of shovel frames, swinging supports for said frames, shovels on sa1d frames,'

toothed standards, hingedly attached to the rear ends of 'the frames, boxes slidable and shaft mounted transversely of the main frame, a'plurality of brackets mounted on said shaft and united by universal joints to said boxes, and means for rotating the shaft for withdrawing the shovels from contact with the soil.

. 2. In a cultivator, amain frame, a plurality of shovel framesattached thereto, shovels "supported in,said frames, standards hingedly attached to the rear ofvsaid frames,

tfoot operated means to swing the-frames toward a row, means normally tending to throw the frames awayfrom the row,

toothed sectors on said frames adjacent the standards, pawls slidable on said standards and engaging said frames, levers attached to the tops of theseveral standards," rods connecting said levers and said pawlsfor withdrawlng said pawls from said sectors to permitoblique adjustment of-said shovel frames.

-3; In a cultivator, a main frame, a plurality of-shovel frames attached to saidmain frame, shovels carried by said frame, a plnrality ofjbell: crank levers mounted on the main frame, horizontal threaded bars attached to one extremity of the respective bell crank levers, depending arms attached to said bars and ,to said shovel frames, and

pedals connected to the several opposite arms of the bell-crank levers, for 0011111111111 eating lateral movement to theseveral shovel frames. r t
